How to Prevent Data Loss During OST Migration

OST migration is a critical process when transferring Outlook mailbox data to another system, email client, or file format. Without proper planning, users may experience data loss, missing emails, corrupted folders, or damaged attachments. To ensure a successful migration, it is important to create a backup of the OST file, verify mailbox synchronization, check file integrity, and use a reliable OST migration solution. Professional OST migration tools can help preserve emails, attachments, contacts, calendars, metadata, and folder hierarchy throughout the migration process. Performing a test migration and validating the migrated data afterward can further reduce risks.
